From the Coorg people of Malabar, Southwest India. Known as fanatical Muslims, launched a genocidal attack on the local Hindu in 1921 and though outnumbered almost two to one nearly succeeded in wiping out the Hindus. They used swords like this one.

Reminds me a little of a Ram Dao, but these are much more rare.

I have always had an interest in Southwest India, Kerala and Malabar. One of the cultures I have studied there are the Theyyam. Someday soon I hope to travel there.
